Figure 8: Interfacing the PA4100X with an MRC88 Zones 7 & 8

In this case:

1.Using good quality RCA Stereo Patch Cords, connect the Preamp Outputs of Zone 7 on the MRC88 to the Left and Right Audio Inputs labeled ‘A’ on the rear of the PA4100X.

2.Similar to step 1, connect the Preamp Outputs of Zone 8 on the MRC88 to the Left and Right Audio Inputs labeled ‘B’ on the rear of the PA4100X.

3.Using two 3.5mm Stereo Mini Plug cables, connect the Remote Amp CO1 jack on the rear of the MRC88 to the CI1 jack on the rear of the PA4100X

4.Similar to step 3, connect the Remote Amp CO2 jack on the rear of the MRC88 to the CI2 jack on the rear of the PA4100X.

5.Set the CI Switch (Item #14) to the ON (UP) position.

The Remote Amp CO1 & CO2 (Remote Control Jack) from the MRC88 allows for individual Zone control directly from the Zone 7 & 8 keypads of the MRC88 system. When any one of the zones is turned on, the PA4100X is powered ON. Similarly, when either Zone is powered down, the associated amplifier pair on the PA4100X is put into STANDBY Mode. When both Zones (7 & 8) are powered down, the PA4100X will either go into STANDBY Mode on both amplifier pairs or will be POWERED OFF depending upon the position of the front panel POWER/STANDBY button (IN = STANDBY; OUT = ON/OFF).
